Phoenix LTR4W31 4-Drawer Letter Size Fireproof File Cabinet, 31" Deep

Phoenix® World Class Fireproof File Cabinet, 4-Drawer, Letter Size, 31" Deep

The Phoenix LTR4W31 is a full-depth, four-drawer vertical fireproof file cabinet for organizations that need high-capacity protection for letter-size records. It combines Class 350 1-hour fire protection, impact and explosion resistance, water-resistant drawer construction, and a key-operated plunger lock.

Its 31-inch exterior depth provides longer drawers and greater filing capacity than the compact 25-inch model. Each drawer is independently insulated, helping protect closed drawers even if another drawer is open. Adjustable filing rails, movable dividers, recessed latch handles, and a lock-bypass system make the cabinet practical for active office records. Free white-glove delivery is included, subject to site-access requirements.

Specifications

Why Choose the Phoenix LTR4W31?

• Certified paper-record protection: Class 350 one-hour protection helps keep interior temperatures suitable for paper documents during the rated fire exposure.
• Impact and explosion resistance: The cabinet is tested for structural hazards associated with building fires, including impact and temperature blasts up to 2000°F.
• High protected capacity: Four 26-inch-deep interior drawers provide substantial storage for letter-size records.
• Independently insulated drawers: Closed drawers remain protected even if another drawer is open.
• Water-resistant sealing: A labyrinth sealing system and special gaskets help resist water from sprinklers and fire hoses.
• Flexible access control: The key-operated plunger lock secures the cabinet, while the bypass mechanism allows selected drawers to remain unlocked.
• Media protection: MTC Grade B certification covers CDs, DVDs, USB drives, and memory sticks.

Common Applications

Use the LTR4W31 to protect active letter-size records that must remain accessible in the office but would be difficult, expensive, or impossible to reconstruct after a fire.

• Legal, accounting, and financial records
• Medical and administrative files
• Human resources and personnel records
• Government and municipal documents
• Insurance, mortgage, and real-estate files
• Education and institutional records

Choosing the Right Fireproof File Cabinet

4-Drawer vs. 2-Drawer

Choose the four-drawer LTR4W31 when you need maximum protected filing capacity within a single cabinet footprint. The two-drawer LTR2W31 is easier to place in a private office or smaller records area and has a lower overall height and weight.

31″ vs. 25″ Depth

The 31-inch LTR4W31 provides 26-inch-deep interior drawers for greater filing capacity. Choose the 25-inch LTR4W25 when aisle space, room depth, or tight delivery turns are the greater concern.

Letter vs. Legal Size

The LTR4W31 is built for letter-size records. Choose the wider Phoenix LGL4W31 when you need legal-size filing; the legal cabinet can also be configured for letter-size files but requires additional floor and delivery clearance.

Vertical vs. Lateral Filing

Choose this vertical model when you want high capacity in a narrow 16-7/8-inch-wide footprint. A Phoenix lateral fire file provides wider drawers and more filing orientations but occupies substantially more wall and floor width.

Free White-Glove Delivery

Free white-glove delivery is included with the LTR4W31. Because the cabinet weighs approximately 512 lbs., delivery details must be reviewed before shipment.

• Uncrating and Cleanup: The delivery team uncrates the cabinet and removes the packaging materials.
• Typical Delivery Timing: Allow approximately 7–14 business days, depending on location, carrier scheduling, and site requirements.

• Special Scheduling: Timed, after-hours, weekend, restricted-access, or small-truck service may require advance approval and additional charges.

Missing or inaccurate stair, elevator, doorway, truck-access, or final-placement information may result in additional freight, redelivery, return, or restocking charges. Contact Advanced Filing Concepts before ordering if you are unsure about delivery access.

Frequently Asked Questions

Does the LTR4W31 hold legal-size files?

No. This model is designed for letter-size files. Choose the wider Phoenix LGL4W31 for legal-size filing.

What are the exact dimensions and weight?

The cabinet measures 54″ high by 16-7/8″ wide by 31″ deep and weighs approximately 512 lbs. Each drawer measures 10-1/2″ high by 12-1/4″ wide by 26″ deep.

What does the Class 350 rating mean?

Class 350 identifies fire protection intended for paper records. Phoenix lists the LTR4W31 for one hour of Class 350 protection and associates its World Class fire-file certification with the SP Institute.

Can I protect computer media in this cabinet?

Its MTC Grade B rating covers less heat-sensitive media such as CDs, DVDs, USB drives, and memory sticks. Do not rely on this rating for magnetic tapes, data cartridges, or hard drives; those require Class 125 media protection.

Is the cabinet waterproof?

No. It is water-resistant, not waterproof. Its labyrinth seals and special gaskets are designed to help protect contents from sprinkler and fire-hose spray.

Can some drawers remain unlocked?

Yes. The lock-bypass mechanism allows selected drawers to remain unlocked while the plunger lock secures the other drawers.

Is white-glove delivery included?

Yes. Room-of-choice placement, uncrating, and packaging removal are included when the delivery route and final location meet service requirements. Stairs and unusual access conditions must be disclosed and approved in advance.
